FlLE OR RASP.

SPECIFICATION forming part of Letters Patent No. 445,712, dated February3, 1891.

Application filed December 27, 1890. Serial No. 375,929 No model.)

To wit-0122, it may concern:

Be it known that I, THOMAS N. DALLIS, a citizen of the United States,residing at Spartan burg, in the county of Spartanburg, State of SouthCarolina, have invented certain new and useful Improvements in Files orRasps, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to files or rasps, particularly those of largesize; and the object of my improvement is to afford better facilitiesthan heretofore for the proper and effective manipulation of said raspsto sharpen various parts of plows and other implements by providing saidsharpening-tool with a flat extension made integral therewith at eachend thereof, said extensions being broader at their outer ends andadapted to serve as nondetachable handles for the tool; and theinvention consists in the improved construction of the same, as will behereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a raspor plow-sharpener constructed in accordance with my invention. Fig. 2 isa perspective view of a modification of the same.

On said drawings, A represents the body of the rasp, which is preferablyrectangular in form, and has at each end an extension A made integraltherewith. Said extension at the point a, where it is connected with thebody of the rasp, is wider than the base of the tang with which filesare usually provided, and it is rounded and still broader at its outerend a than at the point of connection a, and in this manner the rasp isprovided with a broad flat extension or handle at one end, to be graspedby the right hand of the operator, and a flat handleat the other end ofsuch form as not to easily slip through the left hand of the operatorwhile using the tool.

To still further increase the facilities for handling and operating therasp, the extensions or handles A at the point of connection a with thebody A are at an angle with said body, one handle being bent up and theother down, so that each one presents a broad fiat surface to receivethe palm of both the right and the left hands of the operatorsubstantially at right angles to the direction of the pressure producedon the tool by the operator. The inclination of the teeth or serrationsbeing on one side of the rasp in the opposite direction of those uponthe opposite side, either one of said sides will be in proper positionfor use by simply reversing the tool end for end, and the handles willassume the position shown in Fig. 2, the turned-up handle being intendedto be grasped by the left hand of the operator.

Having now fully described my invention, I claim- 1. A file or rasphaving its body provided at each end with a flat extension or handleintegral therewith, said flat extension being rounded and broader at itsouter end than at the point of connection thereof with said body,substantially as described.

2. A file or rasp having its body provided at each end With a flatextension or handle integral therewith, said flat handles being bent atan angle to said body, substantially as shown and described.

3. A file or rasp having its body provided at one end with a flatextension or handle integral therewith, said extension being rounder andbroader at its outer end than at the point of connection thereof withsaid body and bent at an angle to said body, substantially as described.

In testimony whereof I affix my sign aturein presence of two witnesses.

THOMAS N. DALLIS.
